Example Best Prices Report - October 2009

To illustrate the content in one of our LiquidMetrix Best Prices reports, here
is a recent sample, with some commentary, of the Best Prices Report for the FTSE-100
index for the calendar month of October 2009.

Best Touch Prices

The table to the right shows the percentage of time each venue posted best, equal best or not best
bid/offer prices. The stats are based on sampling the order book every 5 seconds, ranking the venues
and then averaging these thousands of rankings over the constituents of the index for the whole of
August/September. Some general points:

LSE has the highest At Best Percentage (around 12% of the time LSE has the best price in the market)

By adding up all the 'Best' percentages across the venues we see that around 35% of the time there is a single venue with the best price. About 56% of the time there is a tie with at least two venues offering the same prices

Unsurprisingly, best bid and best offer percentages are pretty much identical

25K Euro Best Prices

The analysis here is similar to that for Best Touch Prices (above) but instead
of comparing simple best
bid/offer prices we match a 25K Euro order up (down) the book and measure the average executed
price. So this gives a fairer indication of best venue for larger aggressive order sizes, albeit
based on visible liquidity only. Some general points:

LSE is now much more dominant

CHIX moves comfortably into second place

TRQX is relegated to a fairly poor third indicating that often its best prices have relatively low amounts of volume

There are far fewer ties (only 22% of the time as opposed to 56% for touch prices) as a 25K EUR order will often match past the first price in the book and in that case the venue with more volume at best and subsequent prices will win

Best Touch Prices Trend

The graph shows the daily percentage best bid prices over September averaged for
each trading day.

LSE has maintained its advantage throughout the month

CHIX has become more competitive and has nearly caught up with LSE by the end of the month

After an initial drop TRQX has stabilized over the remainder of the month

NURO has narrowed it’s gap with BATS and was even slightly ahead of BATS at the end of the month

25K Euro Best Prices Trend

The graph shows the daily percentage best bid prices over October

LSE, CHIX, NURO and BATS are relatively stable throughout the period

TRQX shows a slight drop at the beginning of the month but has since
stabilized around a slightly lower level compared to BATS.
